[0032] Reference Figures 1 to 5 The present utility model provides a laryngoscope blade 100 .
[0033] In an embodiment of the present utility model, the laryngoscope blade 100 includes: a lens body 10, which extends in an arc shape and has an introduction end 11 and a camera end 12 arranged opposite to each other, the lens body 10 is formed with a accommodating cavity 10a, the introduction end 11 is provided with an introduction port 11a connected to the accommodating cavity 10a, and the camera end 12 is provided with an imaging surface 12a; a tongue depressor 20, which is connected to the camera end 12 and extends toward a side away from the introduction end 11; a reinforcing rib 30, which is connected to the tongue depressor 20 and the lens body 10; a liquid blocking portion 40, which is connected to the camera end 12 and is arranged corresponding to the imaging surface 12a.
[0034] Specifically, in this embodiment, the lens body 10 is molded from a medical-grade plastic material. Preferably, the lens body 10 is molded from a transparent medical-grade plastic material. Its cross-section is rectangular and extends in an arc shape to better adapt to the human throat. The lens body 10 is a shell-shaped cavity structure, forming a accommodating cavity 10a. Its two ends are respectively an introduction end 11 and a camera end 12. The introduction end 11 is formed with an introduction port 11a connected to the accommodating cavity 10a. The camera extends into the accommodating cavity 10a through the introduction port 11a. The camera end 12 at the other end is provided with an imaging surface 12a, through which the camera takes pictures. A tongue depressor 20 is connected to the camera end 12 and extends toward a side away from the introduction end 11. The tongue depressor 20 is used to suppress the patient's tongue. A reinforcing rib 30 is connected to the tongue depressor 20 and the lens body 10 to prevent the tongue depressor 20 from being deformed by force. The liquid shield 40 is connected to the imaging end 12 and is disposed in correspondence with the imaging surface 12a. By disposing the liquid shield 40 in correspondence with the imaging surface 12a, the present invention protects the imaging surface 12a when the lens body 10 is inserted into the larynx, preventing secreted liquid from obstructing the imaging area, thereby improving the imaging clarity of the laryngoscope.
[0035] In one embodiment of the present invention, the liquid blocking portion 40 includes a liquid blocking plate 41, which is connected to the lens body 10 and the reinforcing rib 30 and is arranged opposite to the tongue depressor 20. The liquid blocking plate 41, the tongue depressor 20 and the reinforcing rib 30 enclose a liquid-shielding area 100a, and the imaging surface 12a is accommodated in the liquid-shielding area 100a.
[0036] Specifically, the liquid baffle 41, the lens body 10, the reinforcing rib 30 and the tongue depressor 20 are integrally formed through an injection molding process, wherein the liquid baffle 41 and the tongue depressor 20 are spaced apart in an upper and lower manner, that is, when the lens body 10 is inserted into the patient's throat, the tongue depressor 20 is pressed on the patient's tongue, and the liquid baffle 41 is stopped above the patient's tongue. The two cooperate with the reinforcing rib 30 and semi-enclose the periphery of the imaging surface 12a. In this way, when it is extended into the throat, the liquid baffle 41 can not only prevent the secreted liquid from flowing to the surface of the imaging surface 12a, but also can guide the liquid to the side of the tongue depressor 20, so that the imaging effect of the laryngoscope lens 100 is better.
[0037] It is understandable that the liquid blocking portion 40 can also be provided with two liquid blocking plates 41, and the two liquid blocking plates 41, the tongue depressor 20 and the reinforcing ribs 30 are enclosed to form a liquid-proof area 100a, and the imaging surface 12a is accommodated in the liquid-proof area 100a, that is, the two liquid blocking plates 41, the tongue depressor 20, and the reinforcing ribs 30 are arranged around the periphery of the imaging surface 12a. In this way, the liquid blocking portion 40 has a better blocking effect on the secreted liquid, and thus the imaging effect of the laryngoscope blade 100 is better.
[0038] Please see again Figure 4 Furthermore, along the insertion direction of the lens body 10, the liquid baffle 41 is tilted away from the edge of the lens body 10 toward the side of the reinforcing rib 30 to direct the liquid toward the side of the reinforcing rib 30. It is understandable that in actual use, the patient is in a supine position, and the medical staff inserts the lens body 10 into the throat in a vertical direction. At this time, under the action of gravity, the secreted liquid flows through the upper surface of the liquid baffle 41. However, by tilting the edge of the liquid baffle 41 toward the side of the reinforcing rib 30, the liquid can be directed to the side of the reinforcing rib 30, that is, the edge of the imaging surface 12a, to a certain extent through the action of friction. Then, through the guiding effect of the reinforcing rib 30, the liquid is directed to the side of the tongue depressor 20, thereby further preventing the secreted liquid from flowing to the side of the imaging surface 12a.
[0039] Please see again Figure 1 and Figure 3 In one embodiment of the present invention, the edge of the tongue depressor 20 away from the liquid baffle 41 extends in an arc shape. The arc-shaped extension shape can be set according to the group of people who need to use it. By setting the tongue depressor 20 with an arc-shaped edge extension, the laryngoscope blade 100 can be inserted into the patient's throat more smoothly and the patient's discomfort during insertion can be alleviated.
[0040] Please see again Figure 4 and Figure 5 In this embodiment, the camera end 12 also includes a light source surface 12b. Specifically, in actual use, in order to ensure that the camera can image more clearly, the laryngoscope is generally also provided with a movable light source (not shown in the figure). The light source and the camera are inserted into the accommodating cavity 10a together. In the insertion direction along the lens body 10, the light source surface 12b is located in front of the imaging surface 12a, that is, the light source is located at the front end of the camera, and the positions of the two in the horizontal direction are staggered with each other. In this way, in actual use, the light emitted from the periphery of the light source can be avoided from blocking the camera, so that the imaging effect of the camera is further improved.
[0041] Furthermore, along the side of the introduction end 11 to the side of the camera end 12, that is, the insertion direction of the lens body 10, the cross-section of the lens body 10 is gradually reduced. Such a setting can, on the one hand, fix the camera and light source installed in the accommodating cavity 10a, and on the other hand, the insertion of the lens body 10 into the throat is also smoother.
[0042] Furthermore, the laryngoscope blade 100 further includes a fixing buckle 50 formed with the lens body 10. The fixing buckle 50 is located on one side of the introduction end 11 and is used to fix the camera and the main body of the laryngoscope.
[0043] The present invention also proposes a laryngoscope (not shown in the figure), which includes a camera and a laryngoscope blade 100. The specific structure of the laryngoscope refers to the above-mentioned embodiment. Since the present laryngoscope adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the laryngoscope includes a camera (not shown) and a laryngoscope blade 100, and the laryngoscope blade 100 includes a lens body 10, a tongue depressor 20, a reinforcing rib 30 and a liquid blocking portion 40; the lens body 10 extends in an arc shape and has an introduction end 11 and a camera end 12 arranged opposite to each other, the lens body 10 forms a accommodating cavity 10a, the introduction end 11 is provided with an introduction port 11a connected to the accommodating cavity 10a, the camera end 12 is provided with an imaging surface 12a, the camera extends into the accommodating cavity 10a from the introduction port 11a, the tongue depressor 20 is connected to the camera end 12, and extends toward the side away from the introduction end 11, the reinforcing rib 30 is connected to the tongue depressor 20 and the lens body 10, the liquid blocking portion 40 is connected to the camera end 12, and is arranged corresponding to the imaging surface 12a.
